The project uses a handful of components, including several USB ports, LEDs, resistors, and a custom PCB. Once you have everything, you’ll need to solder it all together and reflow the board. If that’s all too complicated, you can order one for $20. The added USB ports beef up the Pi Zero so it’s not much smaller than a standard Raspberry Pi 3, but it’s a slick enough design that it might still be useful for certain projects. Head over to Instructables for the full guide to make it for yourself.
